Patent DE-2419707-A1 (DE)
Title: Prefabricated fencing lattice sections connection - with spanned bars passing through two sections' lengthways bar end loops
Inventor: ZAPF JUERGEN
IPC: E04H17/16
Filed: 1974-04-24
Abstract: The assembly is for joining together prefabricated lattice-work sections to build up a fence, each section comprising two spaced longitudinal bars interconnected by cross bars. There are eye-loops at the ends of the longitudinal bars, set coaxially to each other and couplings are provided by two or more spaced and similarly aligned bars, spanned at the top, one bar in each case being insertable from above through the eye-loops in two adjacent lattice sections. The end parts of the bars in the couplings, which project beyond the lattice sections at the bottom, serve as anchors. The lattice sections may be able to swivel about the coupling bars. Connection is simplified, and less tubular posts are needed.

Title: Telephone exchange network - network built in several superposed planes arranged hierarchically
Inventor: ERNST WOLFRAM DIPL ING
IPC: H04Q3/00
Filed: 1974-06-27
Abstract: The network consists of a radial network of trunk lines corresponding to the network hierarchy; of a mesh network of trunk lines in the highest network plane, and of transversal trunk lines meshing radial network nodes in different planes, deviating from the network hierarchy. When any connections are built-up between nodes in the radial networks and exchanges at their end points, using the normal routes corresponding to the hierarchy rules and also routes by-passing these rules, the number of the by-pass routes per connection is limited. As connection build-up progresses, dialling information is transmitted from the last used exchange to the next exchange to be reached.

Title: Vehicle servo assisted steering - with variable reaction force on steering wheel limited by fixed spring for low speed
Inventor: JABLONSKY ERICH
IPC: B62D5/24
Filed: 1974-07-30
Abstract: The steering control has two opposing control valves mounted on the steering column to regulate the flow of hydraulic fluid to either side of the servo piston, while the other side of the servo piston is connected to the fluid return line. The system is designed so that in the mid position of the steering there is no fluid flow. This reduces the fluid demand to a minimum so that the system can be coupled to a central hydraulic system. The reaction force on the wheel is controlled by a control valve in relation to the pressure difference across the servo piston, with a maximum value of reaction force.

Title: Synchronisation unit for typewriter ribbon - has a swivelable base plate used to guide and correct movement of ribbon
Inventor: KLEFFMANN GUENTER
IPC: B41J33/26
Filed: 1974-10-07
Abstract: The base plate (45) provides a guide surface (46) for limiting the lateral movement of the ink ribbon, a cylindrical pin (48) for aligning the ribbon (11) at right angles to the plate and a thin conical guide pin (49) for forming a small tube.

The base plate can be swivelled about the axis ('A') of cylindrical headed screw (50) so as to produce the necessary tension in the ribbon. The ribbon is driven by a pressure roller, drive roller, and gear wheel which is coupled to a toothed belt.

Title: Brushless linear motor running on DC - has permanent magnets forming moving part and has stationary part with iron core
Inventor: AUGENREICH KLAUS DIPL ING
IPC: H02K41/035
Filed: 1974-10-24
Abstract: The motor is used for low power drives where there is an overriding requirement for a machine without moving contacts, e.g. venetian blinds or drives for toys. The stationary part comprises an iron core (5) carrying a winding (4). The moving part is a permanent magnet assembly (3, 3'). The length proportions are such that the core length (L2) is greater than the winding length (L1) which in turn is greater than the length (L3) traversed by the magnet. The magnet forms a locally concentrated positive field with weaker negative, but not necessarily symmetrical, field on each side. Speed of the magnet is determined by the applied voltage thus the frequency converter required by an a.c. linear motor can be dispensed with. Switching of the coil at the end of each traverse may be limit switches or by a system employing proximity sensors.
